A bone fracture is a medical condition in which a bone breaks. A bone fracture can also occur as a result of certain medical conditions that weaken the bones, such as osteoporosis, certain types of cancer or Osteogenesis Imperfecta.

* Closed fractures are those in which the skin is intact, while open (compound) fractures involve wounds that communicate with the fracture and may expose bone to contamination. Open injuries carry an elevated risk of infection; they require antibiotic treatment and usually urgent surgical treatment (debridement). This involves removal of all dirt, contamination, and dead tissue.
